Low maint. - Great water

Best water filtration I've ever used. I'm so glad I went with a whole-house system instead of just dealing with the kitchen faucet for drinking water. The green sand system removes all traces of iron - completely. The carbon stage removes all traces of the chlorine added by my municipally-supplied water and I love the no-maintenance resin softener. My municipal water comes from large wells full of iron and other minerals as well as a high quantity of lime. Without this system my toilets and tub always had issues with iron streaks, the laundry would yellow, as well and all water fixtures had a constant build-up of calcium. Since I put in the Pelican system I have no yellowing of laundry, no iron streaks anywhere and no caked calcium build up on faucets. There will still be a very light film of what I can assume is very soft calcium build-up on sink basins and the tub, easily removed with soft scrub during regular cleaning. This is so effective and low maintenance, it's easily worth the initial cost.

Mark Hughes was/is amazing. I've been looking for a house water filtration system for awhile and once I spoke with him I was sold. He is extremely knowledgeable, professional, a great listener and all in all an asset to your company. I will be calling him with a few more questions and I know that is just fine with him. Thank you for the great service!

easy installation

we recently purchased a Pelican water filtration system for our new condo and have been pleasantly surprised at how easy the installation was and how effective the carbon filter has been in reducing the natural scaling of our water. I would certainly recommend this system to any one who needs one.

Very good

I worked with Mark Hughes in Buying the correct systems for my home. One of the biggest thing was setting up the electronic head on the Nitrate tank. I would have had a hard time without Mark Hughes. He walked me through the whole menu without Mark I do not know if I could have gotten the system to work correctly. I am thankfully you have Mark Hughes working for you to help me.
